used for raising the materials to the desired height. These stagings areinconvenient in that they permit of the lifting of the materialsdirectly to only one point of the building under construction, fromwhich point the materials have to be transported by hand to the placewhere they are required. The crane of the present invention, on theother hand, permits the delivery of materials to all parts of thebuilding under construction.

Briefly stated, this crane consists of a mast or upright on which isarranged a vertically movable carriage, which supports a boom adapted tobe horizontally displaced on said carriage.

The invention will be better understood by reference to the accompanyingdrawings, illustrating one embodiment of the inventive idea, and inwhich Figure 1 is an elevation of the crane; Fig. 2 is a similarelevation of part of the device drawn to a larger scale; Fig. 3 is aplan view, illustrating the upper end of the movable carriage and theconnection between the same and the horizontally movable frame-work; andFigs. 4 and 5 are details.

Referring to the drawing, M indicates a mast or upright which is securedto the ground or an adjacent structure by any suitable means, as forexample chains A. This mast comprises a plurality of suitable uprightshere shown as four right-angled corner irons A. These uprights areprovided with gussets a which are connected together by tie-rods Z),disposed both vertically and horizontally. On this mast a suitablecarriage is mounted and adapted to move vertically. This carriage may beof any desired construction, but is preferably composed of cross-piecesor rings a and d connected by a plurality of rods B, here shown as four.These rods are connected and supported by a plurality of collars B whichare provided with bosses 2 through which said rods pass. This carriageis vertically displaced by any suitable means, but preferably there isemployed a tackle f, passing through an opening in the top A of the mastand connected to the upper ring 0 of said carriage and operated by aWindlass (not shown). Bearing surfaces, here shown as rollers e, aremounted on said carriage and engage said uprights A. This carriage ispreferably held in any desired position along the mast by suitablelocking means. As here shown these means consist of a plurality ofcatches or cleats g pivoted at 11 to the lower crosspiece or ring d(Fig. 5). These catches or cleats are each provided with a notch 12, andare so constructed as to automatically move into engagement with acorresponding part of the main structure, such as b. When it is desiredto raise or lower the carriage, said catches or cleats are disengagedfrom said tie-rods by means of cords or connections 13, and when thesaid carriage has been moved to the desired position the catches orcleats are released, whereupon they automatically engage the adjacentparts Z). The boom D is mounted on said carriage in any suitable mannerbut preferably there is provided a framework which is horizontallymovable on said carriage and to which said boom is secured. Thisframework preferably consists of two iron uorights C to the upper endsof which is secured a rectangular frame 3. This frame is provided withhousings 4 in which are mounted a plurality of suitably spaced rollers72.. These rollers engage a vertically arranged track or way 5 providedon the upper cross-piece or ring 0. To the lower ends of said upright 0there are secured a plurality of rollers for engagement with the lowercross-piece or ring cl. Referring to Fig. 5, said ring (Z is providedwith a vertically arranged track or way 8 and with a horizontallyarranged track or way 10. Rollers j, mounted in housings 9, (see Fig. 2)engage the horizontal track or way 10 and rollers t' engage the verticaltrack or way 8. Suitably mounted on the upright C is a platform E whichsupports a motor is.

Through this motor the said framework is horizontally movable on thecarriage. This is effected through the intermediary of motor shaft 6, anendless-screw contained in casing 7, a helicoidal wheel mounted on theend of shaft Z and meshing with said endless-screw, and a pinion Zmounted on the other end of said shaft Z, said pinion Z meshing with arack on secured to the ring (Z in any suitable manner.

The load is raised by means of a winch electrically driven by a motor 72mounted on a platform Gr also carried by the irons C. A hoisting chain Fpasses over pulley n fixed to the head of the boom D, then over pulley nand finally winds up on the winch 0, 0 and is stored in the box 1". Themotor 19 also operates a worm driving a wormwheel which is contained inhousing 16 and on the shaft of which worm-wheel is mounted the drum 9 ofthe cable H which elevates the boom D. This cable passes over pulley swhich, like pulley a heretofore referred to, is mounted on the upperring 0. Both the motors is and p are controlled by a switch I.

l/Vhen it is desired to hoist a load of material to a certain height onthe building under construction, the carriage is first adjusted to thedesired vertical position and the hoisting chain F is then lowered. Thematerial is then raised to the predetermined height, the cable H forlifting the boom D being wound upon the drum and the motor 7c is thenoperated for horizontally shifting the frame-work on the carriage, ifthis is desired. The boom is stopped when its free end is exactly abovethe place where the load should be deposited and the hoisting chain isthen lowered to deposit the load.

\Vhat is claimed is 1. In a crane, a mast or upright, a carriage movablevertically on said upright, a framework movable horizontally on saidcarriage, and a boom carried by said framework.

2. In a crane, a mast or upright comprising a plurality of rods, acarriage movable vertically on said upright and provided with verticallyarranged tracks or ways, bearing surfaces mounted on said carriage andengaging said rods, a framework movable horizontally on said carriage,bearing surfaces mounted on said framework and said carriage andengaging said rods, a framework horizontally movable on said carriage,rollers carried thereby and engaging surfaces on said carriage, and aboom carried by said framework.

5. In a crane, a mast or upright, a carriage vertically movable thereon,and com prising a plurality of cross-pieces connected by a plurality ofrods, a rack mounted on one of said surfaces, a framework horizontallymovable on said carriage, a pinion carried by said framework and meshingwith said rack, means imparting movement to said pinion, and a boomcarried by said framework.

6. In a crane, a mast or upright, a carriage vertically movable on saidupright, a catch mounted on said carriage and automatically operated tosecure the same in any desired position, a framework movablehorizontally on said carriage, and a boom mounted on said framework.

7. In a crane, a mast or upright, a carriage vertically movable on saidupright, a catch pivoted to said carriage and automatically operated toengage said upright and to secure the same in any desired position, aframework movable horizontally on said carriage, and a boom mounted onsaid framework.

8. In a crane, a mast or upright, a carriage vertically movable thereonand provided with a vertically and a horizontally arranged track or way,a framework horizontally movable on said carriage, rollers carried bysaid framework and engaging said tracks or ways, and a boom carried bysaid framework.

9. In a crane, a mast composed of a plurality of right-angled beams, acarriage vertically movable on said mast, a plurality of rollers mountedon said carriage and engaging said beams, a framework movablehorizontally on said carriage, and a boom mounted on said framework.

10. In a crane, a mast or upright, a ear riage vertically movablethereon and provided with tracks or ways, a framework horizontallymovable on said carriage, said framework comprising a plurality ofuprights with rollers mounted at each end thereof and engaging saidtracks or ways, and a boom mounted on said framework.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
